2010-12-14fbdev: Fix fb_find_nearest_mode refresh comparisonAndrew Kephart
Refresh rate nearness is not calculated or reset when nearest resolution changes. This patch resets the refresh rate differential measurement whenever a new nearest resolution is discovered. This fixes two error cases; first, wherein the first mode's refresh rate differential is never calculated and second, when the closest refresh rate from a previous nearest resolution is erroneously preserved.

2010-12-01lxfb: Maintain video processor palette through suspend/resumeDaniel Drake
The Geode X driver uses both of the LX's palettes, one for gamma correction and one for colormaps. The kernel driver currently only backs up the one used for colormaps during suspend/resume. If you mess with gamma settings and do a suspend/resume, colors go funny. Fix this by backing up the video proc palette during suspend/resume, alongside the display controller one which is already handled.

2010-12-01video: da8xx: Register IRQ as last thing in driver probing.Caglar Akyuz
Following commit exposed a bug in driver: "fbdev: da8xx/omap-l1xx: implement double buffering" Bug is, if interrupt handler is called before initialization is finished, raster controller is enabled and following register modifications causes hardware to stay in a broken state. By looking at this one may say that proper locking is missing in this driver, and a more proper fix should be prepared. However, aformentioned commit causes a regression in the driver and some fix to current one should be applied first.

Commit b5c26f97ec4a17c65 introduced some breakage for the OLPC XO-1 laptop, differences in the output video signal after the patch caused some problems with the XO's display controller chip. Reviewing of that commit against the AMD Geode LX Data Book, it seems that these bits were being set inversely. In both cases, active high output is denoted by a value of 0.

2010-11-17fbcmap: integer overflow bugDan Carpenter
There is an integer overflow in fb_set_user_cmap() because cmap->len * 2 can wrap. It's basically harmless. Your terminal will be messed up until you type reset. This patch does three things to fix the bug. First, it checks the return value of fb_copy_cmap() in fb_alloc_cmap(). That is enough to fix address the overflow. Second it checks for the integer overflow in fb_set_user_cmap(). Lastly I wanted to cap "cmap->len" in fb_set_user_cmap() much lower because it gets used to determine the size of allocation. Unfortunately no one knows what the limit should be. Instead what this patch does is makes the allocation happen with GFP_KERNEL instead of GFP_ATOMIC and lets the kmalloc() decide what values of cmap->len are reasonable. To do this, the patch introduces a function called fb_alloc_cmap_gfp() which is like fb_alloc_cmap() except that it takes a GFP flag.

2010-11-16fbdev: sh_mobile_lcdcfb: fix bug in reconfig()Arnd Hannemann
The function sh_mobile_fb_reconfig() contained a bug, which caused the line_length to be set wrongly, if a mode with a different X-resolution than the default one was chosen. This caused 1080p24 mode to not work on AP4EVB. Additionally the notifier chain was also called with the wrong mode. This patch fixes this, by using the X-resolution of the new mode instead of the old one to calculate line length and hands over the correct mode to the notifier chain.
